ELECTRICAL CHARACTERISTICS (continued)
(V BATT = 1.2V to 5.5V, V CC = 1.2V to 5.5V, T A = -40°C to +85°C, unless otherwise specified. Typical values are at T A = +25°C.) (Note1)

Note 1: Production testing done at T A = +25°C; limits over temperature guaranteed by design only.
Note 2: The device is powered up by the highest voltage between V BATT and V CC .
Note 3: MR input ignores falling input pulses, which occur within the MR debounce period (t DEB ) after a valid MR reset assertion.
This prevents invalid reset assertion due to switch bounce.
Typical Operating Characteristics
(V BATT = 1.2V to 5.5V, V CC = 1.2V to 5.5V, unless otherwise specified. Typical values are at T A = +25°C.)
